실험 절차

A mixture of 1,3-dihydro-indol-2-one (266 mg, 2 mmol), 5-formyl-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (2-diethylamino-ethyl)-amide (530 mg, 2 mmol) and piperidine (1 drop) in ethanol was heated at 90° C. for 2 hours. The reaction was cooled to room temperature, the resulting precipitate was collected by vacuum filtration, washed with ethanol and dried to give 422 mg (55%) of the title compound as a light yellow solid.
